  • a portion of the information displayed on the second display unit 14 is covered by the image displayed as the background and the rest of the information is displayed according to the information display type. In this way, an analog type display effect is obtained.
  • the control unit 55 controls a display type of the information variously to maximize an effect of the image.
  • the control unit 55 may control the information display type in the various ways described with regard to the first embodiment in order to maximize the effect of displaying the information on the second display unit 14 as the analog type.
